Is it a joke about EV charging in Europe? Like there are super duper chargers for super advanced car batteries and rather good coal and nuclear plants but no good network between them?

[–] HK65@sopuli.xyz 6 points 1 day ago (1 children)

I don't think so, also electric chargers of varying quality are super ubiquitous in Europe.

My little Eastern European hometown of 20k people has two stations of 8 plugs each.

I agree with your point, but I also assume it’s a not a supercharger-grade? Like in China they have quite often supercharger-grade in cities practically everywhere and prices per kilowatt are no different from slow-charging (like 22kW). While in Europe I noticed that price for kWh is different based on charger’s capacity.

It's less based on the capacity, and more on how much time is likely a premium.

E.g. motorway services are more expensive, since people need the power and want to get back on the road. It's exactly the same logic as the price of petrol there.

Makes sense! Thank you!

One of the two is actually a Tesla supercharger
